Inventor: CLARK JEFFREY G
IPC: A61F13/00
Filed: 1992-08-28
Abstract: A wound closure device (30) employs a porous bonding member (36) which receives a flowable adhesive capable of providing long term wound support. The bonding member (36) is positioned by a carrier member (32) that is used to achieve initial apposition of the wound and which may later be removed. An intermediate barrier may be provided between the bonding pad (36) and the wound site.  Alternatively, a rigid applicator may be utilized for positioning the bonding pad (36) at the wound site. The closure device can include a supply of flowable adhesive for adhering the bonding member (30) to the skin of the patient. Suitable flowable adhesives are cyanoacrylates. A form of packaging supports the wound closure member for preapplication of the adhesive and can serve as a part of a sterile barrier package.

IPC: H03L7/18
Filed: 1991-10-18
Abstract: In a frequency synthesizer, a first pulse removing circuit (31) is connected between a reference signal generator (21) and a phase-frequency comparator (24).  A second pulse removing circuit (32) is connected between a variable frequency divider (23) and the phase-frequency comparator.  Responsive to first removing data indicative of a first pulse number, the first pulse removing circuit removes pulses from the reference signal that are equal in number to the first pulse number for a first predetermined cycle to produce a first pulse removed signal.  Responsive to second removing data indicative of a second pulse number, the second pulse removing circuit removes pulses from the divided signal that are equal in number to the second pulse number for a second predetermined cycle to produce a second pulse removed signal.  Responsive to a current command, a current controlling circuit may control current supplied from/to a charge pump circuit (25).  A control circuit may be connected between the phase-frequency comparator and the charge pump circuit.  A switch may be inserted between the loop filter and the voltage controlled oscillator.  When the switch switches off a PLL, a D/A converter supplies a control voltage to the voltage controlled oscillator and a filter capacitor of the loop filter.  The charge pump circuit may comprise a control circuit, a constant current circuit, an integrating circuit, and a sample and hold circuit.

Title: Method and apparatus for desulfurization of a gas
Inventor: HASEBE NOBUYASU
IPC: C01B17/62
Filed: 1993-01-13
Abstract: An alkaline earth bicarbonate is solubilized in water and contacted by a flue gas. The solubilized alkaline earth bicarbonate reacts with the SO2 in the flue gas to form an alkaline earth sulfite which readily precipitates from the water solution and is efficiently separated therefrom. In accordance with the invention, the slurry exiting the desulfurization step is subjected to a heating step which causes soluble alkaline earth bisulfite formed during the desulfurization step to convert to the insoluble sulfite.  The solids are separated from the aqueous phase and subjected to thermal degradation to recover the alkaline earth oxide and SO2. The alkaline earth oxide can be recirculated and reused in the desulfurization process while the SO2, which has practical uses as a precursor in various chemical processes and therefore is of commercial value, is liquified. Thermal degradation of the solids from the desulfurization step is carried out in apparatus which includes a preheater zone, an ignition and heating chamber and a degradation zone. The thermal degradation is carried out in the presence of heated pellets which are themselves inert to the degradation reaction. Preferably, the pellets are heated in the ignition and heating chamber prior to contact with the solids from the desulfurization step.

Title: Swim goggle
Inventor: HOFFMAN NED
IPC: A63B33/00
Filed: 1993-05-28
Abstract: A swim goggle (2) having a bladder construction (30, 32) forming all or part of the perimeter seal between the goggle and the user. In one embodiment of the invention, the goggle includes a finger actuated pump mechanism (38) and an exhaust assembly connected to the bladder. In an alternative embodiment, the bladder is sealed to a reservoir (142) of medium which can be displaced with a finger actuated cam assembly (152). In both embodiments, when the bladder volume is changed the dimension of the goggle seal increases thereby displacing the goggle lenses away from the user's face and increasing the air space in the cavity formed between the goggle and the user's eyes. This increased air space causes a partial vacuum enhancing the integrity of the goggle seal against the user's eye sockets.

Filed: 1995-02-08
Abstract: A method is described for making a fluidized cracking catalyst having in situ highly dispersed metal traps which comprises (a) impregnating particles of a zeolite catalyst by the incipient wetness technique under sub-atmospheric conditions with a mixture of a tin compound and an antimony compound dissolved in an organic solvent,  (b) stirring the impregnated catalyst in paste form while still under sub-atmospheric conditions,  (c) heating the mixed catalyst in the presence of an oxygen-containing gas until dry, and repeating steps (a),  (b) and (c) above until a desired level of said metals in the metal traps is achieved.  In the incipient wetness technique, an appropriate amount of solvent is added to achieve proper transport of organometallic components, precursors of the metal traps, providing at the same time complete wetness of a given amount of catalyst without forming a layer of liquid on top of the catalyst.  The impregnation procedure is usually repeated at least four times to obtain the desired metal loading.

Abstract: Methods and apparatus are disclosed for using information about a calling party's identity or the importance of a call to control the call waiting signal played to a called party that is busy on another call. Upon determining that a called communication station is busy on another call, information about the identity of the calling party is obtained from the calling station. This information is processed to determine call routing treatment, and particularly to determine whether a call waiting signal is to be played for the call and, if so, what type of call waiting signaling is to be played. The called party can determine information about the identity of the calling party from the call waiting signaling, and thus determine whether to interrupt the call in progress to respond to the call waiting signal. In one exemplary embodiment of the invention, information about the calling party's identity is used to provide a distinctive call waiting signal which identifies the caller as being a particular individual or as a member of a particular group of individuals. In another exemplary embodiment of the invention, information about the calling party's identity controls whether a call waiting signal is played to the called party or suppressed.
